Abstract
Weyers acrofacial dysostosis (WAD) is a rare skeletal dysplasia, which is autosomal-dominant, and the clinical symptoms are presented as dental anomalies, polydactyly, nail dystrophy, and short physical stature. It is also termed "Curry‑Hall syndrome" and reported to be linked to genetic mutations mapped on chromosome 4p16, the region reported being commonly associated with a similar genetic syndrome, Ellis-van Creveld (EVC) syndrome. Most individuals with EVC have congenital heart abnormalities, most often atrial septal defects, unlike WAD. In this case, a 15‑year‑old girl presented with onychodystrophy and polydactyly observed in the hands and feet, microdontia, or agenesis of teeth, which were conical in shape, with a short stature. The patient had dystrophy of nails since birth, and physical growth in terms of height did not match the normal growth parameters with respect to age. The patient also had abnormal dentation with conical-shaped teeth, with the rest of the clinical presentations suggestive of WAD.

Identification of Compound Heterozygous EVC2 Gene Variants in Two Mexican Families with Ellis-van Creveld Syndrome. Genes (Basel) 2023; 14:genes14040887. [PMID: 37107645 PMCID: PMC10137610 DOI: 10.3390/genes14040887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 03/06/2023] [Accepted: 04/07/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Ellis-van Creveld syndrome (EvCS) is an autosomal recessive ciliopathy with a disproportionate short stature, polydactyly, dystrophic nails, oral defects, and cardiac anomalies. It is caused by pathogenic variants in the EVC or EVC2 genes. To obtain further insight into the genetics of EvCS, we identified the genetic defect for the EVC2 gene in two Mexican patients. METHODS Two Mexican families were enrolled in this study. Exome sequencing was applied in the probands to screen potential genetic variant(s), and then Sanger sequencing was used to identify the variant in the parents. Finally, a prediction of the three-dimensional structure of the mutant proteins was made. RESULTS One patient has a compound heterozygous EVC2 mutation: a novel heterozygous variant c.519_519 + 1delinsT inherited from her mother, and a heterozygous variant c.2161delC (p.L721fs) inherited from her father. The second patient has a previously reported compound heterozygous EVC2 mutation: nonsense mutation c.645G > A (p.W215*) in exon 5 inherited from her mother, and c.273dup (p.K92fs) in exon 2 inherited from her father. In both cases, the diagnostic was Ellis-van Creveld syndrome. Three-dimensional modeling of the EVC2 protein showed that truncated proteins are produced in both patients due to the generation of premature stop codons. CONCLUSION The identified novel heterozygous EVC2 variants, c.2161delC and c.519_519 + 1delinsT, were responsible for the Ellis-van Creveld syndrome in one of the Mexican patients. In the second Mexican patient, we identified a compound heterozygous variant, c.645G > A and c.273dup, responsible for EvCS. The findings in this study extend the EVC2 mutation spectrum and may provide new insights into the EVC2 causation and diagnosis with implications for genetic counseling and clinical management.

Abstract
Ellis-van Creveld syndrome (EvC) is an autosomal recessive genetic disorder involving pathogenic variants of EVC and EVC2 genes and classified as a ciliopathy. The syndrome is caused by mutations in the EVC gene on chromosome 4p16, and EVC2 gene, located close to the EVC gene, in a head-to-head configuration. Regardless of the affliction of EVC or EVC2, the clinical features of Ellis-van Creveld syndrome are similar. Both these genes are expressed in tissues such as, but not limited to, the heart, liver, skeletal muscle, and placenta, while the predominant expression in the craniofacial tissues is that of EVC2. Biallelic mutations of EVC and EVC2 affect Hedgehog signaling and thereby ciliary function, crucial factors in vertebrate development, culminating in the phenotypical features characteristic of EvC. The clinical features of Ellis-van Creveld syndrome are consistent with significant abnormalities in morphogenesis and differentiation of the affected tissues. The robust role of primary cilia in histodifferentiation and morphodifferentiation of oral, perioral, and craniofacial tissues is becoming more evident in the most recent literature. In this review, we give a summary of the mechanistic role of primary cilia in craniofacial development, taking Ellis-van Creveld syndrome as a representative example.

Abstract
Ellis-Van Creveld is a rare syndrome with characteristic dental and orofacial findings. Dental management of patients with Ellis-Van Creveld syndrome can be complicated by the associated skeletal and cardiac abnormalities. Here, we present the dental and orofacial findings in a patient with Ellis-Van Creveld syndrome, describe a new oral finding, and discuss the dental management considerations.
